Chemical Background and Pharmacology of 1cP-LSD
1cP-LSD is a synthetic derivative of lysergic acid, which occurs naturally in ergot alkaloids. Chemically, it is the condensation product of cyclopropionic acid and LSD, where the cyclopropionyl group is substituted on the NH position of the indole moiety. This molecular modification creates a compound that is structurally nearly identical to LSD but with a slightly different side chain.
The primary hypothesized mechanism of action positions 1cP-LSD as a prodrug for LSD. Like other N-acylated derivatives such as 1P-LSD and 1V-LSD, the cyclopropionyl group is believed to be cleaved off through metabolic processes in the body, resulting in the active molecule LSD. This proposed metabolic pathway explains why the subjective effects of these compounds are essentially indistinguishable from those of classical LSD.
Additionally, 1cP-LSD may act as a weak partial agonist at the serotonin 5-HT2A receptor, known to mediate the psychedelic effects of classical psychedelics. Animal studies using the head-twitch response assay in mice have found that 1cP-LSD has similar potency to other LSD analogues, with behavioral effects closely resembling these structural analogs.
Comparison of LSD and Its Analog Prodrugs
| Compound | Full Chemical Name | Potency Relative to LSD | Duration (Hours) |
|---|---|---|---|
| LSD-25 | Lysergic acid diethylamide | 100% | 8-12 |
| 1P-LSD | 1-propionyl-lysergic acid diethylamide | ~85% | 8-12 |
| 1cP-LSD | 1-cyclopropionyl-lysergic acid diethylamide | ~100% | 8-12 |
| 1V-LSD | 1-valeroyl-lysergic acid diethylamide | ~100% | 8-12 |
Subjective Effects and Experience
The effects of 1cP-LSD are described as virtually identical to those of classical LSD-25, though individual experiences can vary depending on dosage, mindset (set), and environment (setting).
The typical 1cP-LSD duration is comparable to LSD:
- Onset: 20-40 minutes
- Come up: 45-90 minutes
- Peak: 3-5 hours
- Come down: 3-5 hours
- Total duration: 8-12 hours
Common Effects Include:
Positive Effects:
- Euphoria and sense of wellbeing
- Increased creativity and open-mindedness
- Enhanced sensory perception
- Mindfulness and present-moment awareness
- Feelings of unity and connectedness
- Visual effects such as geometric patterns and enhanced color perception
Neutral or Challenging Effects:
- Time distortion
- Difficulty concentrating
- Confusion or thought loops
- Mild nausea during onset
- Increased heart rate and body temperature
- Difficulty sleeping
As with other psychedelics, “set and setting” play a crucial role in shaping the 1cP-LSD experience. A positive mindset and safe environment can greatly influence whether the journey is insightful or challenging.
Potential Risks and Safety Profile
While 1cP-LSD is generally considered to share LSD’s safety profile, it is not without risks. It has no known physical addiction potential and a high therapeutic index, but users should be mindful of both psychological and physical effects.
Psychological Risks
- Bad Trips: Can involve anxiety, paranoia, or panic, particularly in inexperienced users.
- Triggering Latent Conditions: Those with a history of psychosis or mood disorders may face higher risks.
- Hallucinogen Persisting Perception Disorder (HPPD): Rare but possible, involving ongoing visual disturbances.
Physical Side Effects
- Increased heart rate and blood pressure
- Dilated pupils
- Elevated body temperature
- Loss of appetite
- Muscle tension and jaw clenching
- Nausea
Risk Comparison of Psychedelic Substances
| Risk Category | 1cP-LSD/LSD | NBOMe Compounds | Psilocybin Mushrooms |
|---|---|---|---|
| Physical Toxicity | Very Low | High (fatal overdoses documented) | Very Low |
| Psychological Risk | Moderate | High | Moderate |
| Addiction Potential | Very Low | Low | Very Low |
| Lethal Dose Ratio | Extremely High | Low | Extremely High |
Global Legal Status
The legal status of 1cP-LSD varies significantly across jurisdictions.
United States: Not explicitly scheduled, but the Federal Analog Act may apply, treating it as illegal if sold for human consumption.
Europe:
- Germany: Controlled under the NpSG since 2023.
- United Kingdom: Illegal under the Psychoactive Substances Act 2016.
- Sweden: Under review and potential control.
- Netherlands: Grey area, with some tolerated loopholes.
Other Regions:
- Canada and Australia: Likely considered analogs to LSD and controlled.
- South Korea: Temporarily controlled with renewable measures.
Laws shift rapidly for research chemicals like 1cP-LSD, and individuals must stay informed about their country’s regulations.
Harm Reduction Practices
Safe use requires comprehensive harm reduction strategies.
Substance Testing: Essential to ensure purity and avoid dangerous substitutes such as NBOMe compounds. Use reagents or drug checking services.
Set and Setting: Use only in a safe, comfortable environment with trusted people. Avoid if in a negative emotional state.
Trip Sitter: A sober sitter can help ensure safety.
Dosage Considerations:
- Start with a low dose to gauge sensitivity.
- Avoid redosing, as tolerance builds quickly.
- Wait at least 1-2 weeks between sessions.
Contraindications:
Avoid if you have a personal or family history of psychosis, cardiovascular conditions, or if you are pregnant, nursing, or on serotonergic medications.
Frequently Asked Questions
What is the difference between 1cP-LSD and LSD-25?
They are distinct compounds, but 1cP-LSD acts as a prodrug to LSD, producing nearly identical effects.
How long does 1cP-LSD last?
The experience typically lasts 8-12 hours, with onset in 20-40 minutes and peak effects around 3-5 hours.
What is a standard 1cP-LSD dosage?
A standard dose is 75-150μg, while microdoses range between 10-20μg. Start lower to assess sensitivity.
Is 1cP-LSD legal in the US?
It is not explicitly scheduled but may fall under the Federal Analog Act if intended for human consumption.

Yes, challenging experiences can occur, especially with poor preparation or high doses.
Conclusion
1cP-LSD represents the ongoing innovation in psychedelic compounds and the challenges of regulating them. It mirrors LSD in both potential benefits and risks, but its research chemical status means much remains unknown. Legal landscapes are shifting, and responsible harm reduction is essential for anyone engaging with it.
Safe practice requires testing, careful attention to set and setting, and thoughtful integration of experiences. As research into psychedelics expands, more insights will emerge, shaping our understanding of these powerful substances.
